New chat by number

[albakhtari]

I almost finished this feature, but I wasn't able to link the newChat() function from main.js to the main menu file.
I had great fun developing this feature. But for public release, I think it's better if @Zzombiee2361 does it so that it doesn't mess up the rest of the code.
I used electron-prompt, and the following method to create a new chat:

const openChat = number =>  {
       const number_link = document.createElement("a");
      link.setAttribute("href", `whatsapp://send?phone=${number}`);
      document.body.append(number_link);
      link.click();
      document.body.removeChild(link);
};
